To all whom it may concern:

Be it known that I, Roscon A. COFFMAN, a citizen of the United States, residing at Indianapolis, Marion county, and VState of Indiana, have invented and discovered certain new and useful Improvements in Lubricant Catching and Defiecting Means for Piston-Rods, of which the following is a specification.

My invention relates to lubricant catching and retaining means for pistons of in ternal combustion engines, and its object is to provide means for preventing the lubricant, or the fuel carrying the lubricant, the lubricant is injected into the cylinder from being dispersed against the walls of the cylinder and to effect its direct application to and retention upon the piston rod, thereby econoniizing in material and obtaining better lubrication. This invention is particularly applicable to two-cycle engines.

With this object in view, my invention is embodied in preferable form in the construction hereinafter described and illustrated in the accompanying drawings. In these drawings, Figure 1 is a vertical section through a part of the cylinder and crank case of a two-cycle internal combustion engine showing my invention applied to the connecting rod, and Fig. v2, a detail vertical section at right angles to Fig. 1.

Referring to the drawings, 1 indicates the crank case, 2, a cylinder and 3, a piston therein. A connecting rod 4 is pivoted to the piston and the invention relates particularly to means for more eifectively utilizing the lubricant in oiling the bearings of this connecting rod and guiding the lubricant along the rod to such bearings.

Copies of this patent may be obtained for ve cents each, by addressing the commissioner of Patente The cylinder 6 .through which the lubricant, rnixed with a body of liquid fuel, is injected from a suitable passage way 8. Carried by the connecting rod 'on opposite faces thereof are deiiecting andcatching vanes or otherwise rod and the plane faces of which extend at right angles to the faces of the rod. These vanes constitute deiectors and they project from the rods suiliciently to cover the path of the fluid carrying the lubricant injected through the opening whereby as the latter is carried into the cylinder it will strike against these deiiectors and be retained and carried along the connecting rod to the bearings thereof, thus eifectually preventing the dispersion of the lubricant against the wall of the cylinder and the consequent loss of utilization of part of the lubricant.

Having thus described what I claim is In combination with the piston rod of an internal combustion engine and its 4containing chamber to which to be admitted, lubricant deflecting means carried by the said rod and consisting of vanes extending on opposite sides of the rod and into the path of the injected lubricant with the planes of their faces at right angles to the path of said injected lubricant.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, this 23rd day of March, A. D. 1918.
